SPIRAL LOCK is a strong connecting fitting with a very long fastening travel, especially conceived to join bed sides and panels. Consisting of a threaded M8 dowel and of a cylindric joint, SPIRAL LOCK guarantees a strong fastening function without damaging the housing into the panel. This is made possible by the particular plastic cap which features the cylindric joint, thus maximising the resistance. An inner anti-rotating device guarantees the steadiness of the joint and therefore its extremely long efficiency. SPIRAL LOCK can be mounted on relatively thin panels, with a minimum thickness of 19mm. The locking function can be carried out with an exagonal S6 key or even faster with a cordless screwdriver. The fastening travel is minimum 5 mm. SPIRAL LOCK is also conceived for installation through automatic machinery.
